I am using Angular 12.2.17 and DevExtreme 20.1.9, and I encountered the following error when using the dx-scheduler component:

Additionally, I see another error related to triggerResize

<div class="container py-5 my-5">
<dx-scheduler [dataSource]="appointments"
[currentDate]="currentDate">
</dx-scheduler>
</div>


@Component({
selector: 'inspections-new',
templateUrl: 'inspections-new.component.html',
})
export class InspectionsNewComponent {
appointments = [{
text: "Website Re-Design Plan",
startDate: new Date("2016-04-25T01:30:00.000Z"),
endDate: new Date("2016-04-25T03:30:00.000Z")
}, {
text: "Book Flights to San Fran for Sales Trip",
startDate: new Date("2016-04-25T09:00:00.000Z"),
endDate: new Date("2016-04-25T10:00:00.000Z")
}];

currentDate = new Date(2016, 4, 25);
}


Expected Outcome: I expected dx-scheduler to render appointments without errors.\
